Follow-up: Homebrew and Thumbnails on OS X

Some additions to the imagemagick-transform.properties file were introduced as a bug-fix to 4.1.6 Enterprise Edition and subsequently 4.2.d Community and all newer versions of Alfresco. The additions were:

img.coders=${img.root}\\modules\\coders

img.config=${img.root}\\config

img.gslib=${img.root}\\lib

As ImageMagick installed via Homebrew uses a slightly different folder structure, we'll need to override these three properties in alfresco-global.properties in order to restore thumbnail functionality in OS X.
